by the way the switch is a HP Procurve 8212.
thanks

Try:

spanning-tree port_number edge-port

I have auto-edge-port or
admin-edge-port as options amongst other things like bpdu-filter etc
thanks

Here is the description for both command. Use the one you need specifically

With the auto-edge-port feature, the identification of edge ports is automatic. Auto-edge-port- feature is enabled by
default on ports. The port will look for BPDUs for 3 seconds; if there are none it begins forwarding packets and port is
set as Edge, if there are BPDUs, it sets the port as non-Edge.
As an admin, if you do not care about the 3 sec delay, auto-edge-port is an easy end recommended setup.


For a manual setup of Edge ports, enable admin-edge-port on ports connected to end nodes. During spanning tree
establishment, ports with admin-edge-port enabled transition immediately to the forwarding state. If a bridge or switch
is detected on the segment, the port automatically operates as non-edge. Admin-edge-port is disabled by default.

I have configured as an admin-edge-port but still getting STP has blocked the trunk and the server drops out at that point for a second while STP reenables that port.

any ideas appreciated.
thanks

I dont want to disable spanning tre for the whole switch just for the ports. Is there any reason why my 4X10GB trunk ports are getting blocked by STP randomly. some days never other days constantly. It has been intermittant until recently and I just need to stop this for these trunks only
thanks

Please post your switch config and logging info during these events.

see attached images

Looks like a trunking problem.

Which physical ports make up trunk 4?

And the ports for trunk 4 go to a server, right?

Physical ports are:
TRK4 = I1 and I2
TRK5 = I3 and I4

These ports are going from the core to a DELL M8024 fabric on the back of a M1000e blade.

was working fine for weeks with no changes to my knowledge

Please post the output of a "show lacp".

I just ran the command and the result was no lacp ports found.

Well, it's possible that you're not using LACP to build the trunks.

What about a "show trunk"?

see image below
 

I looks like I1 and I2 are members of a static trunk.

If the other end isn't manually aggregating the ports, there's your problem.

That's why I like to use LACP. Much easier to troubleshoot.

I beleive the DELL side is manually aggregating as we had issues initially they would not talk unless they were the same, so we set the M8024 to static.
Does that sound right.
Shoud I be looking to disable Spanning tree on the trunk port or as you suggested to trouble shoot the DELL switch further?
thanks again!

If you disable spanning tree you will most likely end up with a broadcast storm.

I would investigate the configuration at the other end.

Turned out to be a fault at the other end (the DELL switches passing through) even though I was assured that was correct, we managed to get a result in the end :(
